For any surface of any lens, the profile curve length within the effective half diameter affects the ability of the surface to correct aberration and differences between optical paths of light in different fields of view.

Herein the weak refractive power means the absolute value of the focal length of one specific lens is greater than 10. When at least one lens among the second to the sixth lenses has weak positive refractive power, it may share the positive refractive power of the first lens, and on the contrary, when at least one lens among the second to the sixth lenses has weak negative refractive power, it may fine turn and correct the aberration of the system.

In an embodiment, the seventh lens could have negative refractive power, and an image-side surface thereof is concave, it may reduce back focal length and size. Besides, the seventh lens can have at least an inflection point on at least a surface thereof, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The plastic lenses may reduce the weight and lower the cost of the system, and the glass lenses may control the thermal effect and enlarge the space for arrangement of the refractive power of the system. In addition, the opposite surfaces (object-side surface and image-side surface) of the first to the seventh lenses could be aspheric that can obtain more control parameters to reduce aberration. The number of aspheric glass lenses could be less than the conventional spherical glass lenses, which is helpful for reduction of the height of the system.

The driving module can be a voice coil motor (VCM), which is used to move the lens for focusing, or can be an optical image stabilization (OIS) component, which is used to lower the possibility of having the problem of image blurring which is caused by subtle movements of the lens while shooting.

Such effect can be achieved by coating on at least one surface of the lens, or by using materials capable of filtering out short waves to make the lens.

An object-side surface 212 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 214 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 212 and the image-side surface 214 both have an inflection point.

The second lens 220 has negative refractive power and is made of plastic. An object-side surface 222 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 224 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 222 and the image-side surface 224 both have an inflection point.

An object-side surface 242, which faces the object side, is a concave aspheric surface, and an image-side surface 244, which faces the image side, is a convex aspheric surface. The object-side surface 242 and the image-side surface 244 both have an inflection point.

The fifth lens 250 has positive refractive power and is made of plastic. An object-side surface 252, which faces the object side, is a concave surface, and an image-side surface 254, which faces the image side, is a convex surface.

An object-side surface 272, which faces the object side, is a concave surface, and an image-side surface 274, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, for the seventh lens 270, the object-side surface 272 has two inflection points, and the image-side surface 274 has an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 280 is made of glass and between the seventh lens 270 and the image plane 290. The infrared rays filter 280 gives no contribution to the focal length of the system.

Third Embodiment

As shown in FIG. 3A and FIG. 3B, an optical image capturing system of the third embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 310, an aperture 300, a second lens 320, a third lens 330, a fourth lens 340, a fifth lens 350, a sixth lens 360, a seventh lens 370, an infrared rays filter 380, an image plane 390, and an image sensor 392. FIG. 3C is a transverse aberration diagram at 0.7 field of view of the third embodiment of the present application.

The first lens 310 has positive refractive power and is made of plastic. An object-side surface 312 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 314 thereof, which faces the image side, is a concave aspheric surface.

The second lens 320 has negative refractive power and is made of plastic. An object-side surface 322 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 324 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 322 and the image-side surface 324 both have an inflection point.

The third lens 330 has positive refractive power and is made of plastic. An object-side surface 332 thereof, which faces the object side, is a convex surface, and an image-side surface 334 thereof, which faces the image side, is a convex aspheric surface. The object-side surface 332 has two inflection points, and the image-side surface 344 has an inflection point.

The fourth lens 340 has positive refractive power and is made of plastic. An object-side surface 342, which faces the object side, is a convex aspheric surface, and an image-side surface 344, which faces the image side, is a convex aspheric surface. The object-side surface 342 has an inflection point.

The fifth lens 350 has negative refractive power and is made of plastic. An object-side surface 352, which faces the object side, is a concave surface, and an image-side surface 354, which faces the image side, is a convex surface. The object-side surface 352 and the image-side surface 354 are both aspheric surface. The image-side surface 354 has an inflection point.

The sixth lens 360 has positive refractive power and is made of plastic. An object-side surface 362, which faces the object side, is a convex surface, and an image-side surface 364, which faces the image side, is a convex surface. The object-side surface 362 has an inflection point, and the image-side surface 364 has four inflection points. Whereby, incident angle of each field of view for the sixth lens can be effectively adjusted to improve aberration

The seventh lens 370 has negative refractive power and is made of plastic. An object-side surface 372, which faces the object side, is a concave surface, and an image-side surface 374, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 372 has two inflection points, and the image-side surface 374 has an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 380 is made of glass and between the seventh lens 370 and the image plane 390. The infrared rays filter 390 gives no contribution to the focal length of the system.

In the third embodiment, the optical image capturing system of the third embodiment further satisfies ΣPP=58.6192 mm; and f1/ΣPP=0.2267, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the third embodiment further satisfies ΣNP=−49.6153 mm; and f2/ΣNP=0.1254, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of the sixth lens 360 to other negative lenses.

Fourth Embodiment

As shown in FIG. 4A and FIG. 4B, an optical image capturing system 40 of the fourth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 410, an aperture 400, a second lens 420, a third lens 430, a fourth lens 440, a fifth lens 450, a sixth lens 460, a seventh lens 470, an infrared rays filter 480, an image plane 490, and an image sensor 492. FIG. 4C is a transverse aberration diagram at 0.7 field of view of the fourth embodiment of the present application.

The first lens 410 has positive refractive power and is made of plastic. An object-side surface 412 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 414 thereof, which faces the image side, is a concave aspheric surface. The image-side surface 414 has two inflection points.

The second lens 420 has negative refractive power and is made of plastic. An object-side surface 422 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 424 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 422 and the image-side surface 424 both have an inflection point.

The third lens 430 has positive refractive power and is made of plastic. An object-side surface 432 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 434 thereof, which faces the image side, is a convex aspheric surface. The object-side surface 432 has two inflection points, and the image-side surface 434 has an inflection point.

The fourth lens 440 has positive refractive power and is made of plastic. An object-side surface 442, which faces the object side, is a concave aspheric surface, and an image-side surface 444, which faces the image side, is a convex aspheric surface. The image-side surface 444 has an inflection point.

The fifth lens 450 has negative refractive power and is made of plastic. An object-side surface 452, which faces the object side, is a concave aspheric surface, and an image-side surface 454, which faces the image side, is a convex aspheric surface. The image-side surface 454 has two inflection points.

The sixth lens 660 has positive refractive power and is made of plastic. An object-side surface 462, which faces the object side, is a convex surface, and an image-side surface 464, which faces the image side, is a convex surface. The object-side surface 462 and the image-side surface 464 both have two inflection points. Whereby, incident angle of each field of view for the sixth lens can be effectively adjusted to improve aberration.

The seventh lens 470 has negative refractive power and is made of plastic. An object-side surface 472, which faces the object side, is a concave surface, and an image-side surface 474, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 472 has an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 480 is made of glass and between the seventh lens 470 and the image plane 490. The infrared rays filter 480 gives no contribution to the focal length of the system.

In the fourth embodiment, the optical image capturing system of the fourth embodiment further satisfies ΣPP=56.0883 mm; and f1/ΣPP=0.2233, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the fourth embodiment further satisfies ΣNP=−87.3758 mm; and f2/ΣNP=0.0585, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of the sixth lens 460 to other negative lenses.

Fifth Embodiment

As shown in FIG. 5A and FIG. 5B, an optical image capturing system of the fifth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 510, an aperture 500, a second lens 520, a third lens 530, a fourth lens 540, a fifth lens 550, a sixth lens 560, a seventh lens 570, an infrared rays filter 580, an image plane 590, and an image sensor 592. FIG. 5C is a transverse aberration diagram at 0.7 field of view of the fifth embodiment of the present application.

The first lens 510 has positive refractive power and is made of plastic. An object-side surface 512, which faces the object side, is a convex aspheric surface, and an image-side surface 514, which faces the image side, is a concave aspheric surface. The object-side surface 512 and the image-side surface 514 both have an inflection point.

The second lens 520 has negative refractive power and is made of plastic. An object-side surface 522 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 524 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 522 has an inflection point, and the image-side surface 524 has two inflection points.

The third lens 530 has positive refractive power and is made of plastic. An object-side surface 532, which faces the object side, is a convex aspheric surface, and an image-side surface 534, which faces the image side, is a concave aspheric surface. The object-side surface 532 and the image-side surface 534 both have an inflection point.

The fourth lens 540 has positive refractive power and is made of plastic. An object-side surface 542, which faces the object side, is a convex aspheric surface, and an image-side surface 544, which faces the image side, is a convex aspheric surface. The object-side surface 542 has two inflection points.

The fifth lens 550 has negative refractive power and is made of plastic. An object-side surface 552, which faces the object side, is a concave aspheric surface, and an image-side surface 554, which faces the image side, is a convex aspheric surface. The object-side surface 552 has two inflection points, and the image-side surface 554 has an inflection point.

The sixth lens 560 can have positive refractive power and is made of plastic. An object-side surface 562, which faces the object side, is a convex surface, and an image-side surface 564, which faces the image side, is a concave surface. The object-side surface 562 has two inflection points, and the image-side surface 564 has four inflection points. Whereby, incident angle of each field of view for the sixth lens 560 can be effectively adjusted to improve aberration.

The seventh lens 570 has negative refractive power and is made of plastic. An object-side surface 572, which faces the object side, is a concave surface, and an image-side surface 574, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, the object-side surface 572 has two inflection points, and the image-side surface 574 has an inflection point, which may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 580 is made of glass and between the seventh lens 570 and the image plane 590. The infrared rays filter 580 gives no contribution to the focal length of the system.

In the fifth embodiment, the optical image capturing system of the fifth embodiment further satisfies ΣPP=77.2534 mm; and f1/ΣPP=0.3608, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the fifth embodiment further satisfies ΣNP=−316.9994 mm; and f7/ΣNP=0.0188, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to other negative lenses.

Sixth Embodiment

As shown in FIG. 6A and FIG. 6B, an optical image capturing system of the sixth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 610, an aperture 600, a second lens 620, a third lens 630, a fourth lens 640, a fifth lens 650, a seventh lens 660, a seventh lens 670, an infrared rays filter 680, an image plane 690, and an image sensor 692. FIG. 6C is a transverse aberration diagram at 0.7 field of view of the sixth embodiment of the present application.

The first lens 610 has positive refractive power and is made of plastic. An object-side surface 612, which faces the object side, is a convex aspheric surface, and an image-side surface 614, which faces the image side, is a convex aspheric surface. The object-side surface 612 has an inflection point.

The second lens 620 has negative refractive power and is made of plastic. An object-side surface 622 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 624 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 622 and the image-side surface 624 both have an inflection point.

The third lens 630 has positive refractive power and is made of plastic. An object-side surface 632, which faces the object side, is a convex aspheric surface, and an image-side surface 634, which faces the image side, is a convex aspheric surface. The object-side surface 632 has an inflection point.

The fourth lens 640 has positive refractive power and is made of plastic. An object-side surface 642, which faces the object side, is a convex aspheric surface, and an image-side surface 644, which faces the image side, is a convex aspheric surface. The object-side surface 642 has two inflection points.

The fifth lens 650 has negative refractive power and is made of plastic. An object-side surface 652, which faces the object side, is a concave aspheric surface, and an image-side surface 654, which faces the image side, is a convex aspheric surface. The object-side surface 652 and the image-side surface 654 both have two inflection points.

The sixth lens 660 can have positive refractive power and is made of plastic. An object-side surface 662, which faces the object side, is a convex surface, and an image-side surface 664, which faces the image side, is a convex surface. The object-side surface 662 has two inflection points, and the image-side surface 664 has three inflection points. Whereby, incident angle of each field of view for the sixth lens 660 can be effectively adjusted to improve aberration.

The seventh lens 670 has negative refractive power and is made of plastic. An object-side surface 672, which faces the object side, is a concave surface, and an image-side surface 674, which faces the image side, is a convex surface. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 680 is made of glass and between the seventh lens 670 and the image plane 690. The infrared rays filter 680 gives no contribution to the focal length of the system.

In the sixth embodiment, the optical image capturing system of the sixth embodiment further satisfies ΣPP=62.7420 mm; and f1/ΣPP=0.2381, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the sixth embodiment further satisfies ΣNP=−88.6984 mm; and f7/ΣNP=0.0806, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to the other negative lenses to avoid the significant aberration caused by the incident rays.

Seventh Embodiment

As shown in FIG. 7A and FIG. 7B, an optical image capturing system of the seventh embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 710, an aperture 700, a second lens 720, a third lens 730, a fourth lens 740, a fifth lens 750, a seventh lens 760, a seventh lens 770, an infrared rays filter 780, an image plane 790, and an image sensor 792. FIG. 7C is a transverse aberration diagram at 0.7 field of view of the seventh embodiment of the present application.

The first lens 710 has positive refractive power and is made of plastic. An object-side surface 712, which faces the object side, is a convex aspheric surface, and an image-side surface 714, which faces the image side, is a concave aspheric surface. The object-side surface 712 and image-side surface 714 both have an inflection point.

The second lens 720 has negative refractive power and is made of plastic. An object-side surface 722 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 724 thereof, which faces the image side, is a concave aspheric surface. The object-side surface 722 and the image-side surface 724 both have an inflection point.

The third lens 730 has positive refractive power and is made of plastic. An object-side surface 732, which faces the object side, is a convex aspheric surface, and an image-side surface 734, which faces the image side, is a concave aspheric surface. The object-side surface 732 and the image-side surface 734 both have an inflection point.

The fourth lens 740 has positive refractive power and is made of plastic. An object-side surface 742, which faces the object side, is a concave aspheric surface, and an image-side surface 744, which faces the image side, is a convex aspheric surface. The object-side surface 742 has an inflection point.

The fifth lens 750 has negative refractive power and is made of plastic. An object-side surface 752, which faces the object side, is a convex aspheric surface, and an image-side surface 754, which faces the image side, is a concave aspheric surface. The object-side surface 752 and the image-side surface 754 both have two inflection points.

The sixth lens 760 can have positive refractive power and is made of plastic. An object-side surface 762, which faces the object side, is a convex surface, and an image-side surface 764, which faces the image side, is a concave surface. The object-side surface 762 has two inflection points, and the image-side surface 764 has an inflection point. Whereby, incident angle of each field of view for the sixth lens 760 can be effectively adjusted to improve aberration.

The seventh lens 770 has negative refractive power and is made of plastic. An object-side surface 772, which faces the object side, is a concave surface, and an image-side surface 774, which faces the image side, is a concave surface. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 780 is made of glass and between the seventh lens 770 and the image plane 790. The infrared rays filter 780 gives no contribution to the focal length of the system.

In the seventh embodiment, the optical image capturing system of the seventh embodiment further satisfies ΣPP=74.3451 mm; and f1/ΣPP=0.3344, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the seventh embodiment further satisfies ΣNP=−4865.9186 mm; and f7/NP=0.0013, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to the other negative lenses to avoid the significant aberration caused by the incident rays.

Eighth Embodiment

As shown in FIG. 8A and FIG. 8B, an optical image capturing system of the eighth embodiment of the present invention includes, along an optical axis from an object side to an image side, a first lens 810, a second lens 820, a third lens 830, an aperture 800, a fourth lens 840, a fifth lens 850, a seventh lens 860, a seventh lens 870, an infrared rays filter 880, an image plane 890, and an image sensor 892. FIG. 8C is a transverse aberration diagram at 0.7 field of view of the eighth embodiment of the present application.

The first lens 810 has positive refractive power and is made of plastic. An object-side surface 812, which faces the object side, is a concave aspheric surface, and an image-side surface 814, which faces the image side, is a convex aspheric surface. The object-side surface 812 and image-side surface 814 both have an inflection point.

The second lens 820 has negative refractive power and is made of plastic. An object-side surface 822 thereof, which faces the object side, is a convex aspheric surface, and an image-side surface 824 thereof, which faces the image side, is a concave aspheric surface.

The third lens 830 has positive refractive power and is made of plastic. An object-side surface 832, which faces the object side, is a convex aspheric surface, and an image-side surface 834, which faces the image side, is a concave aspheric surface. The object-side surface 832 and the image-side surface 834 both have an inflection point.

The fourth lens 840 has negative refractive power and is made of plastic. An object-side surface 842, which faces the object side, is a concave aspheric surface, and an image-side surface 844, which faces the image side, is a convex aspheric surface. The object-side surface 842 and the image-side surface 844 both have an inflection point.

The fifth lens 850 has positive refractive power and is made of plastic. An object-side surface 852, which faces the object side, is a convex aspheric surface, and an image-side surface 854, which faces the image side, is a convex aspheric surface. The object-side surface 852 has two inflection points.

The sixth lens 860 can have positive refractive power and is made of plastic. An object-side surface 862, which faces the object side, is a concave surface, and an image-side surface 864, which faces the image side, is a convex surface. The object-side surface 862 and the image-side surface 864 both have an inflection point. Whereby, incident angle of each field of view for the sixth lens 860 can be effectively adjusted to improve aberration.

The seventh lens 870 has negative refractive power and is made of plastic. An object-side surface 872, which faces the object side, is a concave surface, and an image-side surface 874, which faces the image side, is a concave surface. The image-side surface 874 has two inflection points. It may help to shorten the back focal length to keep small in size. In addition, it may reduce an incident angle of the light of an off-axis field of view and correct the aberration of the off-axis field of view.

The infrared rays filter 880 is made of glass and between the seventh lens 870 and the image plane 890. The infrared rays filter 880 gives no contribution to the focal length of the system.

In the eighth embodiment, the optical image capturing system of the seventh embodiment further satisfies ΣPP=80.7833 mm; and f1/ΣPP=0.3779, where ΣPP is a sum of the focal lengths of each positive lens. It is helpful to share the positive refractive power of one single lens to other positive lenses to avoid the significant aberration caused by the incident rays.

The optical image capturing system of the eighth embodiment further satisfies ΣNP=−138.2578 mm; and f7/ΣNP=0.0605, where ΣNP is a sum of the focal lengths of each negative lens. It is helpful to share the negative refractive power of one single lens to the other negative lenses to avoid the significant aberration caused by the incident rays.
